I must apologise for using the term authenticated. A Freudian slip from MQA, which I considered to be a fraud from the very start. The correct word is certification. If a product is not certified by Roon, it won’t work. You get a red flag.
Roon certification is intended first and foremost to ensure that Roon enabled products work as they are meant to, simply and fault-free. That has always been my experience. I’ve used Devialet Expert Pro for 6 years and Roon Ready was the best thing that happened to it.
